RESILIENT WHEEL.`

Specication of Letters Patent.

Patented Mar. 18, 1913.`

To all wiz-0m 'it may concern Be it` known that I, JOSEPH KoHLEn', a citizen of the United States of America, and a resident of Chicago, in the county of Cook, State of Illinois, have invented certain new and useful Improvements in Resilient Vheels, of which the following is a specification.

` This invention relates to that t-ype of resilient wheels in which an annular pneumatic cushion is arranged between the tire and-hub portions of the wheel to provide an intermediate resilient connection between the parts. And the present improvement has for its object to provide a simple and eflicient structural formation and arrangement of parts whereby the same can be conveniently taken apart for repair and replacement, and a subsequent. reassembly eiected in a like ready and convenient manner.

A further object is to provide a convenient and substantial means for connecting the tire and hub portions together in a fixed and concentric relation in case of a punctureand -deiiation of the intermediate pneumatic cushion, all as will hereinafter more fully appear.

In the accompanying drawings: Figure l, is a side elevationv of a `wheel embodying the present improvements, with parts removed and others in section. Fig. 2, is a central section of the outer annular saddle for the pneumatic cushion, detached. Fig. 3, is a detail transverse section, on line m-w, Fig. 1. Fig. 4, is a similar view, on line f, Fig. 1.

Similar reference numerals indicate like parts in the several views. V

Referring to the drawings, 1 represents a portion of the axle upon which the hub 2 of the wheel is mounted in any usual manner to have rotation independent of the axle.

In the present construction the hub 2 is provided at its inner end with a fixed bearing collar 3, and at its outer end has connection with a separable bearing collar 4, which is preferably formed as a part of the usual housing 5 that incloses the attaching nuts orglikeimealls by which the hub and' axle are held from end'wise"disengagementin.Y

the present class of wheels.

6 are counterpart inner and vouter -disks formed with central orifices adapted to fit the periphery of the cylindrical bod)7 por-V tion of the hub, with the disks in bearing engagement against the respective collars 3 and 4 above described. Said inner and outer disks 6, have the usual separated relation shown, so as to provide an annular space surrounding the body of the hub 2 and adapted to contain the annular pneumatic cushion hereinafter described, and

also provide a guide for the outer tire member to hold the same from any side movement. p

7 are a counterpart pair of annular late members or rings individual to the dis s 6, aforesaid and arranged in t-he same planes as said disks to constitute separate outer'l annular portions or sections of the sarne. Said parts are held together in a separable manner by a circularly arranged series of offset radial'ears 8 preferably formed on the disks as shown, and b v the transverse vstud boltshereinafter described, and which pass through orifices formed in the ears S and plate members 7 aforesaid.

9, are radially disposed corrugations in the side disks 6, for imparting lateral stift'- ness to the same.4 i

10 is the tire member of the Wheel of any same in a plane at right-angles to the axis of rotation of the parts. And as usual in the present type of wheels, the independent movement of the tire member 10 and its side platos 1l just described, is governed and restricted by a' series of enlarged oritices 12 formed in the side plates 11 and adapted to encompass the transverse studbolts above referred to, and by their greater size as compared with that of said bolts, i

permit the required amount of movement.

13 are the series of stud bolts above referred to, arranged in a circular cluster concentric With the axis of rotation ofthe wheel, and each consist-ing preferably of an ordinary screw-threaded bolt, the shank of which carries a sleeve 14, by which distance is imth'eir immediatevaccessories. In the present construction-the number ofoitset ears 8 are less than the number of transverse stud'bolts 13, preferably one to two as shown, and s0 p oselpnVA the annular plate members 7 and*` that. only a portion of said bolts are individual to said offset ears 8, the remainder of said boltsl being attached solely to the annular plate members Tfinterniediate of the ottset ears S, as illustrated in Fig. 1. Vith the described arrangement the assembled relation of the wheel parts is maintained by the last described portion of the transverse bolts l-. while the first. described portion of said bolts 13 are released to permit the removal of one 0r the other of the. central disks G, for access to the interior of the wheel in repairing the annular pneumatic` cushion, and other wheel parts located therein.

15 is the annular elastic cushion heretofore referred to, and which is formed in any usual manner and from any suitable pliable material. l

16 are counterpart annular rings formed of vmetal or like rigid material, and secured to the inner portion of the` annular cushion 15, aforesaid.

17 are outwardly extending holding flanges formed 'on the annular rings 1G, aforesaid.

18 are a pair of counteriiartannular disks, the central openings of which fit the cylindrical ,main body of the hub 2, over which they slip and havel abutment against the inner faces of the annular disks 6, before described.

15) are inwardly extending holding flanges formed on the disks 18 and adapted for holding engagement with the outwardly extending flanges 1T of the rings 16, above described, to securely hold the annular elastic cushion 15 in proper position.

20 is a distance sleeve interposed between t-he aforesaid `annular disks 8 to impose proper separated relation thereon, and in addition provide an inner bearing for the annular cushion 15, as shown.

21 are a series of transverse bolts passing through the vhub collars 3 and 4, the disks (l and 18, and an inturned annular flange 2Q of the distance sleeve 20 to securely clamp the parts together when assembled.

23 is an annular bearing saddle formed with a coneaved inner surface for bearing engagement with the. transversely curved periphery of the annular elastic cushion 15 aforesaid. Said saddle is preferably formed of plate metal and i'n two substantiallyx counterpart sections'whlch meet and engage with each other at the median line of` the saddle as shown, andqii'eferably by means of an offset flange on the one section receiving the unflanged edge of the other` as shown.

24 are outwardly extendingJ side fianges on same, and receive the thrust. therefrom and -1n turn transmit the saine to the annular elastic cushion 15 in the actu-.i1 use of the wheel.

Q5 are a series of transverse orifices formed in the. annular plate members T, and in the side plates 11 of the tire member 10, and with the orifices adapted to register, when the respective parts are in concentric rela tion. In the present improvement said orifices 25 are adapted to receive locking bolts E2G of any ordinary and suitable construction, to firmly secure the described wheel parts from any independent movement. This provision is intended for use in case the pneumatic cushion 15 becomes entirely disabled and it is desired to rctum to the garage on a wheel rendered inelastic by the present provision.

Having thus fully described my said invention what l claim as new and desire to secure by Letters Patent, is

l. ln a resilient wheel, the` combination of an outer tire member having inwardly extending side plates. an inner hub member, an annular elastic cushion interposed between said tire and hub members, side disks secured to the hub member to inclose said cushion and provide a guide for the outer tire member, said side disks comprising central inner portions and outer annular portions connected together by offset ears, a plurality of transverse means connecting said outer ainiular portions together independent ot said ott'set. ears, a plurality of transverse means connecting said outer annular portions together and extending through said offset cars. and means for prevent-ing undue independent movement. of the tire member in relation to the hub member. the same comprising a series of' enlarged orifices in theV side plates of the outer tire member` said.orifices encircling the transverse means aforesaid, substantially as set fort-h.
